To all whom it may concern:

1 Be it known that l, Wimmer F. Winn, a citizen of the United States, residin at Toledo, in the county of Lucas and tate of lOhio, haveinvented certain new and useful improvements in Car-Door lchs, of

which the following is a specification.

This invention relates to door-locking devices for railway cars or the like and has lo for its principal object to provide improvements in the means or mechanism commonly provided for holding and releasing the drop doors ofthe cars, being particularly adapted for use with cars of the twin i5 hopper type. Another object is to provide means cooperating with a transversely arranged pair of doors whereby both of such doors may be suitably supported and conveniently loched without the employment of 2o chains, toggles, or other winding mechanism. @ther objects are to provide a mechai nism of the type specified, conveniently Alocated both with respect to the doors of the Y car and the car structure itself, and within easy access of the` (workmen. With such general and other incidental objects in view the invention consists of the arrangement, formation and combination of parts as will be herein described and finally claimed.

ln the accompanying drawings which show a preferred embodiment of the invention, Figure 1 is a fragmentary side elevational view of the lower corner of one of the hoppers of a coal car of the twin hopper type with the mechanism of the present invention applied thereto. Figure 2 is a transverse sectional view through a portion of this hopper showing the present locking mechanism substantially in plan view., the to view bein arrow 2, Figure 1. Figure 3 is an end elevational View of a portion of the hopper with the mechanism applied, this view be ing seen in the direction of the arrow .3, t5 Figure l.

Referring. to these drawings, the side of the hopper which may also be considered as an extension of the side of the car, is denoted by the nral 1, the bottom of the hopper being denoted by the numeral` v2. Thediopperas shown is that commonly emloyed on cars of the twin hopper type, hai ing the hopper door 2 inclined to form a chute for tli'e discharge of the contents by gravity. Such hoppers are ordinarily provided at each end of the car and there are customarily two such hoppers at each end, arran d side by side as indicated-at 3 and lin hoppers are dehned by hopper end sheets 5, with an intervening space which isoccupied by the center sill construction 6 of the car.`

'Each of the hoppers is closed by means of a door 8, these doors being set upon an inclined plane substantially vat right angles to the plane of the bottom of the'hopper or chute plate 2. The doors are hinged or pivoted along their upperv edgesy at 9 tothe `car body, the free edges 10 being arranged to swing away from the open ends ofthe chute plates 2 when the doors are opened.. No special mechanism is provided for the mechanical swinging of the doors `into closed positions as it has been found that igure 5. Thev inner ends of theseare closed the objects of the of rivets 12. This bracket has a staple or other lock-engaging member 13 adixed to it and the door carries a pivoted locking member in the'form of ahoolr lll which is arranged to latch over the staple 13 'when the doors are pulled shut, thus holding the doors in closed position without the intervention of any unnecessary parts. When the hooks la are in holding position the hook lock or dog 15 which is made in cam shape and pivoted to the brachet 1l bymeans of a rivet lo, is rotated about its pivot so as to Contact the point 17 of the'hoolr and prevent the accidental release of the same. Formed integral with the cam 15 and on the opposite side of the pivot it is an extension 18 which is provided for forcing the eccentric cam'into or out of hard engagement with the point 17 of the hook 14.

The extension 18 constitutes a shoulder, which may be engaged by any suitable form of tool for forcibly rotating the cam either into or out of contact with the back of the lhook 14.

It has been before explained that two doors are arranged side by side as indicated in-dotted lines' in Figure 5. These are hin ed independently to the car body but the inges are in axial alignment so that the two doors may be swung in unison. This is further provided for by means of a trans- Verse beam 7 which extends across the outer faces 4vof the two doors, substantially from sidel to side of the car or hoppers. The beam is inade in the form of a structural channel and the doors are both secured to this common beam which serves as a' stiiener for them and hold them against bulgin from the load. The support of the free edges of the doors against the hopper openings when the doors are closed, is at the ends of the beam 7 only, hence it will be appreciated that lthis beam which spans practically the entire width of the car must be of consider- ,able strength.

The door-locking hooks 14 are pivoted to the doors through the medium of a pivot casting or bracket 19 which is connected to the door plate by means, of the rivets20 and to the beam 7 by means of the rivets 21, this casting /tyiigl together. e Adoor plates extend substantially to the outer face of the hopper, and Ythe beam 7 ends also substantially at the same place. The door-locking mechanism lies in a lane, and is operable 1n that plane, just outslde of the lines of the hopper, the hook portion. of the mechanism being ar- .ranged to swin partly along the outer end of the door an partly along the outer face of the hopper and into engagement with the staple 13 when the doors are in closed positions. The bracket 19, forming a connection between the beam 7 and the door plate, overreaches the edge of the door and extends beyond the end of the beam so that yits outer portion lie's outside of the outer face ofthe hopper or car side.- The hook 14 is pivoted to this bracket by means ofthe bolt 22, there being a pair of walls 23 and 24 formed upon the bracket 'in such manner as to provide a hook-accommodating space therebetween'. The pivot bolt 22 passes'Y transversely ofhthe car through both of these walls, the hook thus swinging in a plane substantially at ri ht angle to the plane .of the door. -B the aforedescribed arrangement considerable weight is saved and economy eected.

The doors for such Acars arepreferably -provided with out-turned marginal flanges of the marginal flange.

the beam and the door plate such as shown in the drawings. For this reason it is preferable that the stiiening beam such as 7 should not extend outwardly beyond the end of the door, but that 1t should be stopped olf just inside of the line The bracket 19 is then secured to the channel 7 and constitutes an extension or arm 'which extends over the out-turned flange. The door supporting mechanism is operable between this arm and a relatively ixedtportion of the car body.

While Figures 1, 2 and 3 show the details of the lock mechanism upon one end of the- 4beam 7 only, it is to be understood that the other end of the beam is similarly equipped, the outer face of the other hopper having a similar bracket and hook arran ment. This construction is denoted by the s owing in dotted lines of the two brackets 19 in Fi ure 5.
